Abstract

The seat cushion mounting mechanism of the utility model includes a main body, a fixed pin, a connecting seat, a push-pull member, and a control handle. The fixed pin is fixedly mounted on the main body, and the connecting seat is pivotally mounted on the main body and has a slide groove. The push-pull member can be slidably accommodated in the slide groove of the connecting seat, and the control handle is pivotally connected to the push-pull member and can rotate relative to the connecting seat to drive the push-pull member to extend or retract relative to the slide groove. When the control handle is not operated to extend the push-pull member, the push-pull member abuts against the fixed pin, so that the connecting seat cannot rotate relative to the main body; when the control handle is operated to retract the push-pull member, the push-pull member leaves the fixed pin, so that the connecting seat can rotate relative to the main body. In this way, the control handle is operated to drive the push-pull member to abut against or away from the fixed pin, so as to control the connecting seat to rotate or not rotate relative to the main body.

Description

Seat cushion mounting mechanism

Technical Field

The utility model relates to a seat cushion of a bicycle, a scooter and a baby walker, and in particular to a seat cushion mounting mechanism. The special structural design of the seat cushion can lift the seat cushion relative to a seat tube, so that parts (such as batteries) arranged under the seat cushion are exposed, so that the rider can take out the parts and replace them.

Background technique

PCT International Patent No. WO2016171532 discloses a bicycle seat angle adjustment device, which includes a fixing part, a housing, and an adjustment unit. The fixing part has a fixing frame fixed to the bicycle frame and a brake pad; the housing is covered on the upper end of the fixing part in a hinged manner. The adjustment unit is arranged on the housing, and the adjustment unit includes a stopper, an elastic device and a control rod, the stopper surrounds the brake pad, the elastic device provides an elastic force acting on the stopper, and the control rod is used to adjust the position of the stopper. When the rider operates the control rod, the control rod drives the stopper away from the brake pad, and at the same time compresses the elastic device to accumulate elastic force, so that the bicycle seat can rotate relative to the fixing frame of the fixing part to adjust the angle of the bicycle seat. Once the angle of the bicycle seat is adjusted, the rider can release the control rod, so that the elastic device releases the elastic force to push the stopper and the brake pad to approach each other and combine, so that the bicycle seat cannot rotate relative to the fixing frame of the fixing part.

As can be seen from the above, the bicycle seat angle adjustment device disclosed in the previous case is installed between the bicycle seat cushion and the telescopic seat tube to adjust the tilt angle of the bicycle seat cushion, and the telescopic seat tube is used to adjust the height of the bicycle seat cushion. If the rider wants to take out the parts (such as batteries) in the telescopic seat tube, the seat cushion must be disassembled from the telescopic seat tube to take out and replace the parts in the telescopic seat tube. However, the above operation steps are complicated and the operation is very inconvenient. Therefore, the bicycle seat angle adjustment device disclosed in the previous case still has room for improvement in structure.

Utility Model Content

In view of the above-mentioned deficiencies, the main purpose of the present invention is to provide a seat cushion installation mechanism, whose special structural design can lift the seat cushion relative to the seat tube to expose the parts arranged under the seat cushion, so that the rider can take out the parts and replace them.

In order to achieve the above-mentioned main purpose, the seat cushion mounting mechanism of the utility model includes a body, a fixing pin, a connecting seat, a push-pull member, and a control handle. The body has a receiving groove. The fixing pin is fixedly arranged in the receiving groove of the body. The connecting seat can be pivotally arranged on the body between a first position and a second position, and the connecting seat has a slide groove. The push-pull member can be slidably accommodated in the slide groove of the connecting seat, and the push-pull member has a supporting end. The control handle is pivotally connected to the push-pull member and can rotate relative to the connecting seat between a locking position and an unlocking position to drive the push-pull member to move relative to the slide groove between an extended position and a retracted position. When the assembly seat is in the first position and the control handle is in the locking position so that the push member is in the extended position, the abutment end of the push member abuts against the fixing pin, so that the assembly seat is maintained in the first position and cannot rotate relative to the main body; when the assembly seat is in the first position and the control handle is in the unlocking position so that the push member is in the retracted position, the abutment end of the push member leaves the fixing pin, so that the assembly seat can rotate toward the second position relative to the main body; when the assembly seat is in the second position and the control handle is in the locking position so that the push member is in the extended position, the fixing pin is not blocked by the abutment end of the push member, and the assembly seat can rotate toward the first position relative to the main body.

Through the above-mentioned technical features, the seat cushion mounting mechanism of the utility model operates the control handle to drive the abutting end of the push member to abut against the fixing pin, so that the assembly seat cannot rotate relative to the main body, or operates the control handle to drive the abutting end of the push member away from the fixing pin, so that the assembly seat rotates relative to the main body, and the assembly seat drives the seat cushion to flip upward relative to the seat tube, so that the parts (such as batteries) arranged under the seat cushion are exposed, so that the rider can take out the parts and replace them.

Preferably, the abutting end of the push member has an abutting recess for stably abutting against the fixing pin.

Preferably, the abutting end of the push-pull member has a guide arc surface opposite to the abutting recess, and when the assembly seat rotates from the second position relative to the body to the first position, the guide arc surface abuts against the fixing pin, so that the push-pull member retracts relative to the slide slot until the abutting recess abuts against the fixing pin. In this way, the push-pull member can be automatically reset by the guidance of the guide arc surface, and the abutting recess abuts against the fixing pin again, so that the rider does not need to continuously operate the control handle to rotate from the unlocked position to the locked position.

Preferably, the assembly seat has a fixing hole; the control handle has a handle portion, a slot provided in the handle portion, a safety latch, and an elastic member, the safety latch can be slidably provided in the slot between an insertion position and a disengagement position, and the elastic member provides an elastic force to force the safety latch toward the insertion position; when the safety latch is in the insertion position, the safety latch is inserted into the fixing hole of the assembly seat, so that the control handle is maintained in the locking position, and when the safety latch is in the disengagement position, the safety latch is disengaged from the fixing hole of the assembly seat, so that the control handle can be moved from the locking position to the unlocking position. In this way, the safety latch is used to prevent the rider from accidentally touching the handle portion of the control handle, so as to improve the safety in use.

Detailed ways

The applicant first explains that throughout the entire specification, including the embodiments described below and the claims of the patent application, the terms related to directions are based on the directions in the drawings. Secondly, in the embodiments and drawings to be described below, the same component numbers represent the same or similar components or their structural features.

Referring to FIG. 1 , a seat cushion mounting mechanism 1 of the first embodiment of the present invention is installed between a seat cushion 10 and a seat tube 13. The seat cushion 10 shown in FIG. 1 has a cushion body 11 and two seat rails 12 spaced apart at the bottom of the cushion body 11. In this embodiment, the seat cushion 10 can be (but not limited to) one of the components of a bicycle, a scooter, or a baby walker.

As shown in FIGS. 2 and 3 , the seat cushion mounting mechanism 1 of the first embodiment of the present invention includes a body 20 , a fixing pin 30 , a set of receiving seats 40 , a push member 61 , a control handle 65 , an elastic member 68 , and a detent rod 69 .

The body 20 is integrally connected to the top of the seat tube 13, and the body 20 can also be connected to the top of the seat tube 13 by bolts or other fixing methods, which are not limited here. The body 20 has a first pivot hole 21 passing through, a receiving groove 22 adjacent to the first pivot hole 21, and two holes 23 oppositely arranged and connected to the receiving groove 22.

Two ends of the fixing pin 30 are respectively inserted into the holes 23 of the body 20 and fixed in the receiving groove 22 of the body 20 .

The assembly seat 40 has a collar 41, the collar 41 has a sleeve hole 42, a slide groove 43 adjacent to the sleeve hole 42, and a long slot hole 44 transversely connected to the slide groove 43, and the long slot hole 44 has a high end H and a low end L. The assembly seat 40 also has two pivot portions 45 extending from the collar 41, each pivot portion 45 has a second pivot hole 46.

As shown in FIG2 , during actual assembly, the second pivot holes 46 of the assembly seat 40 are aligned with the first pivot holes 21 of the body 20 , and two pivot rods 47 and 48 are inserted through the first pivot hole 21 and the second pivot holes 46 , so that the assembly seat 40 can be pivoted to the body 20 rotatably between a first position P1 as shown in FIG3 and a second position P2 as shown in FIG5 . Please continue to refer to FIG2 , and then a support tube 50 is inserted through the sleeve hole 42 of the collar 41 of the assembly seat 40 , and the collar 41 is tightened with a screw S so that the support tube 50 is fixed in the sleeve hole 42 , and then two clips 51 are respectively pressed against the two ends of the support tube 50 , and then a screw 52 is inserted through and fixed to the clips 51 and the support tube 50 , so that the clips 51 respectively clamp and fix the seat bows 12 of the seat cushion 10 as shown in FIG1 .

The push member 61 has a placement end 62, a support end 63, and a through hole 64 disposed between the placement end 62 and the support end 63. As shown in FIG3, the support end 63 has a support recess 631 for supporting the fixing pin 30, and a guide arc surface 632 opposite to the support recess 631.

As shown in FIG. 2 , the control handle 65 has a handle portion 66 and two pivot holes 67 oppositely disposed at one end of the handle portion 66 , wherein the handle portion 66 has a hollow slot 661 for the screw S to pass through.

In this embodiment, the elastic member 68 is a compression spring. As shown in FIG. 3 , the elastic member 68 is accommodated in the slide slot 43 of the assembly seat 40 , one end of the elastic member 68 abuts against the bottom of the slide slot 43 , and the other end of the elastic member 68 abuts against the placement end 62 of the push member 61 , so as to provide an elastic force acting on the push member 61 .

As shown in FIGS. 2 and 3 , during actual assembly, the elastic member 68 and the push member 61 are sequentially placed into the slide groove 43 of the assembly seat 40 , and the through hole 64 of the push member 61 corresponds to the long slot hole 44 of the assembly seat 40 , and the pivot holes 67 of the control handle 65 correspond to the long slot hole 44 of the assembly seat 40 , and then the detent rod 69 is sequentially inserted into one of the pivot holes 67 of the control handle 65 , the long slot hole 44 of the assembly seat 40 , and the through hole 64 of the push member 61 , and then passes through the other pivot hole 67 of the control handle 65 and is fixed by a fixing plate C, so that the control handle 65 and the push member 61 are pivotally connected to each other and rotate relative to the assembly seat 40 between a locked position P3 as shown in FIG. 3 and an unlocked position P4 as shown in FIG. 4 . During the rotation process, the control handle 65 can drive the detent rod 69 to move laterally between the high end H and the low end L of the long slot hole 44 of the assembly seat 40, and then drive the push member 61 to move relative to the slide slot 43 of the assembly seat 40 between an extended position P5 as shown in Figure 3 and a retracted position P6 as shown in Figure 4 through the detent rod 69.

In actual operation, as shown in FIG. 3 , when the rider has not yet pulled the handle 66 of the control handle 65 , the assembly seat 40 is located at the first position P1 and the control handle 65 is located at the locking position P3. At this time, the detent rod 69 is located at the low end L of the long slot hole 44 of the assembly seat 40 , so that the push member 61 is located at the extended position P5 and is firmly pressed against the fixing pin 30 with the pressing recess 631 , so that the assembly seat 40 is maintained at the first position P1 and cannot rotate relative to the body 20 , so that the positioning effect can be achieved, allowing the rider to sit safely on the cushion body 11 of the seat cushion 10 as shown in FIG. 1 .

Continuing with the above description, when the rider applies a force to pull the handle 66 of the control handle 65 upward, the control handle 65 rotates from the locked position P3 shown in Figure 3 to the unlocked position P4 shown in Figure 4. At this time, the detent rod 69 is displaced from the low end L of the long slot hole 44 to the high end H, and drives the push member 61 to move from the extended position P5 shown in Figure 3 to the retracted position P6 shown in Figure 4, so that the abutment recess 631 of the push member 61 leaves the fixing pin 30, and the elastic member 68 is compressed by the placement end 62 of the push member 61 to accumulate elastic force.

In this case, as shown in FIG. 4 , the body 20 and the assembly seat 40 are in a non-fixed state, that is, the assembly seat 40 can rotate from the first position P1 shown in FIG. 4 to the second position P2 shown in FIG. 5 , and form different pivot angles with the body 20. Moreover, the assembly seat 40 can also drive the seat cushion 10 to flip upward to the state shown in FIG. 6 , so that the parts (such as batteries) disposed under the seat cushion 10 are exposed, so that the rider can take out the parts and replace them.

Once the parts are replaced, the force applied to the handle 66 of the control handle 65 is released, so that the control handle 65 rotates from the unlocked position P4 of FIG. 5 to the locked position P3 of FIG. 7, and the elastic force released by the elastic member 68 acts on the push member 61, so that the push member 61 moves from the retracted position P6 of FIG. 5 to the extended position P5 of FIG. 7, so that the assembly seat 40 rotates from the second position P2 of FIG. 7 to the first position P1 of FIG. 3 under the action of gravity. 8, when the assembly seat 40 continues to rotate toward the first position P1, the guide arc surface 632 of the push member 61 will abut against the fixed pin 30, and the push member 61 is guided by the guide arc surface 632 to retract relative to the slide groove 43 until the abutting recess 631 abuts against the fixed pin 30 again (as shown in FIG. 3), and the body 20 cannot rotate relative to the assembly seat 40 and remains in the first position P1. In this way, the push member 61 can automatically reset through the guidance of the guide arc surface 632, so that the abutting recess 631 abuts against the fixed pin 30 again, so that the rider does not need to continue to operate the control handle 65 to rotate from the unlocked position P4 shown in FIG. 5 to the locked position P3 shown in FIG. 3.

However, the seat cushion mounting mechanism 1 is not limited to that disclosed in this embodiment. Please refer to FIG. 9. The seat cushion mounting mechanism 2 of the second embodiment of the utility model is substantially the same as the first embodiment in terms of structure, and the main difference is that this embodiment provides another assembly seat 70 and a control handle 80. In this embodiment, the assembly seat 70 has a fixing hole 71 disposed at the bottom, and the control handle 80 has a handle 81, a slot 82 disposed in the handle 81, a safety latch 83, and an elastic member 84. The safety latch 83 can be slidably disposed in the slot 82 between an insertion position P7 as shown in FIG. 9 and a disengagement position P8 as shown in FIG. 10, and the elastic member 84 is accommodated in the slot 82 and provides an elastic force to keep the safety latch 83 in the insertion position P7.

In actual operation, when the rider applies a force to pull the safety pin 83 downward, the safety pin 83 is displaced from the insertion position P7 shown in FIG. 9 to the disengagement position P8 shown in FIG. 10 , at which time the safety pin 83 is disengaged from the fixing hole 71 of the assembly seat 70 , and the elastic member 84 is compressed by the safety pin 83 to accumulate elastic force, so that the control handle 80 can rotate relative to the assembly seat 70 . Once the rider releases the force applied to the safety pin 83 , the elastic force released by the elastic member 84 acts on the safety pin 83 , so that the safety pin 83 is displaced from the disengagement position P8 shown in FIG. 10 to the insertion position P7 shown in FIG. 9 , so that the safety pin 83 is inserted into the fixing hole 71 of the assembly seat 70 , so that the control handle 80 cannot rotate relative to the assembly seat 70 .

Thus, the design of the safety pin 83 and the elastic member 84 provided in this embodiment can prevent the rider from accidentally touching the handle 81 of the control handle 80, thereby improving the safety of use. The method of operating the control handle 80 to rotate the assembly seat 70 relative to the body 20 is exactly the same as the above steps, and will not be repeated here.

In summary, the seat cushion mounting mechanisms 1, 2 of the present invention can drive the abutting end 63 of the push member 61 to abut against the fixing pin 30 by operating the control handles 65, 80, so that the assembly seats 40, 70 cannot rotate relative to the body 20, or can drive the abutting end 63 of the push member 61 away from the fixing pin 30 by operating the control handles 65, 80, so that the assembly seats 40, 70 can rotate relative to the body 20, so that the assembly seats 40, 70 drive the seat cushion 10 to flip upward relative to the seat tube 13, so that the parts (such as batteries) arranged under the seat cushion 10 are exposed, so that the rider can take out the parts and replace them.
